Step 1
Start Photoshop CS and make sure no images are open. If your
photoshop is already open and you have done some work in
it...closing Photoshop and opening it again before starting an
action is a good idea, or else the action may not work...just a tip
;)

Step 2Unzip the
PuzzleAction1_0.zip file, save the picture puzzle01.psd
somewhere on your harddrive and install the actionset.
Step 3
Open the file puzzle01.psd (again, make sure NO OTHER images
are open).

Step 4
Open the image that you want to apply the effect to. This image must
be in the foreground.

Step 5
The image is very large (2560 x 1920 pixels). If the action is used
on a large image the jigsaw puzzle pieces will be very small. Before applying
the effect in this example I resized the image to 1000 x 750 pixels
to make the pieces a little bigger.

Step 6Click on the "Puzzle #2" action button. Click 'Continue' on
the first dialog box if your images.

Step 7In the next dialog box you click 'Stop' to clean up your puzzle
mesh. Hide the 'Picture layer' by clicking on the eye on that layer
and make the 'Puzzle Template' layer active.

Step 8If you look at the puzzle mesh you can see that something is not
right on the left and right sides.

(Click on the images to see a larger version)

Use the eraser tool (Ctrl+E) to delete the unwanted parts of the
mesh on the left side. Below you can se the result:

(Click on the image to see a larger version)

We could also do the same on the right side, but the pieces will
look a little odd. I choose to crop the image:

(Click on the image to see a larger version)

Now you can tidy up the mesh on the right side with the erase tool.
I also cropped the image once more to make the bottom pieces a
little bigger.

Step 9Make 'Picture Layer' visible again and restart the action.
You'll now have an image looking somthing like this:

If you plan to stop here and use the image without scaling it down,
I suggest that you make the 'Puzzle Template' layer active and
adjust the Layer opacity to around 60 - 70%.

Step 10Next we'll make a simple black border around the picture. Create
a new layer and make it active. Press CTRL+A to select all and then
Edit > Stroke and use the following settings:

Step 11
Now we will remove some of the puzzle pieces. First make the 'Puzzle
Template' layer active.

Select pieces of the jigzaw puzzle by selecting the magic wand tool
and clicking in the picture.

Step 13
Hide 'Picture Layer', make the top layer active (the layer you
created in step 10) and press SHIFT+CTRL+E to merge the visible
layers. Unhide 'Picture Layer' and flatten the image. Double click
the background layer and name it 'Picture Layer'.

Step 14
Add a new layer and position it under 'Picture Layer'. Make the
background color of the new layer white. Make the 'Picture Layer'
active again and use the erase tool to delete the parts of the mesh
and the frame that you don't need anymore.

Step 15
Delete the new layer you added in step 14. You'll now have a picture
looking something like this.
